You're a headhunter. You've translated Chewbacca's CV from Wookiee growls to English, but the translations are scattered across 6 separate items. Time to reconstruct them into a proper CV object.

This challenge teaches you how to aggregate multiple items back into a single structured object.

What you'll practice:

  • Using the Aggregate node to combine multiple items
  • Accessing aggregated data with array indices
  • Rebuilding structured objects from collected data

Your Task

  1. 1Copy the exercise below
  2. 2Paste into your n8n editor (Ctrl+V)
  3. 3Solve it — use hints if you get stuck
  4. 4Check the solution when done

You have 6 translated items. Use the Aggregate node to collect them, then rebuild the CV object.

Your task:

  1. Add an Aggregate node after Combine Results
    • Set "Aggregate" to "All Item Data"
  2. Add an Edit Fields node to extract each translation by index:
    • name: {{ $json.data[0].translation }}
    • species: {{ $json.data[1].translation }}
    • homeworld: {{ $json.data[2].translation }}
    • age: {{ $json.data[3].translation }}
    • role: {{ $json.data[4].translation }}
    • employer: {{ $json.data[5].translation }}

Expected output:

{
  "name": "Chewbacca",
  "species": "Wookiee",
  "homeworld": "Kashyyyk",
  "age": "234 years",
  "role": "Co-Pilot",
  "employer": "Millennium Falcon"
}

Hints

  1. Add an Aggregate node after Combine Results
  2. In the Aggregate settings, set "Aggregate" to "All Item Data"
  3. Add an Edit Fields node after Aggregate
  4. Create 6 string fields, each accessing the translation by index:
    • name: {{ $json.data[0].translation }}
    • species: {{ $json.data[1].translation }}
    • homeworld: {{ $json.data[2].translation }}
    • age: {{ $json.data[3].translation }}
    • role: {{ $json.data[4].translation }}
    • employer: {{ $json.data[5].translation }}

Explanation

What is the Aggregate node?

The Aggregate node collects multiple items into a single item. When you set it to "All Item Data", it creates an array called data containing all the items that flowed into it.

The workflow flow:

Combine Results (6 items)
     ↓
Aggregate (1 item with data array)
     ↓
Edit Fields (extract translations)
     ↓
1 CV object

Understanding the aggregated data:

After the Aggregate node, your data looks like:

{
  "data": [
    {"field": "name", "value": "RAAAAWRGWAWGGR", "translation": "Chewbacca"},
    {"field": "species", "value": "WWWRRRAAAGH", "translation": "Wookiee"},
    ...
  ]
}

Accessing by index:

The expression $json.data[0].translation accesses:

  • $json - the current item's data
  • .data - the array of collected items
  • [0] - the first item (index 0 = name)
  • .translation - the translated value

The result:

You now have Chewbacca's CV translated into readable English! The final step is to format this into a recommendation email.
